Georg Christoph Lichtenberg was a German physicist, satirist, and Anglophile. He was the first person in Germany to hold a professorship explicitly dedicated to experimental physics. He is remembered for his posthumously published notebooks, which he himself called Sudelbücher, a description modelled on the English bookkeeping term "waste books" or "scrapbooks", and for his discovery of the tree-like electrical discharge patterns now called Lichtenberg figures.
